Should I get rid of tiers? $4 flat rate? (Patreon)

With the first of the month coming up, I was wondering what everyone's opinion on this would be. 

If I got rid of tiers, then all WIPS and polls would be accessible to all patrons! But I would have to adjust prices of course. Vote and let me know please! The results won't necessarily mean I'll make the change before this next month, I'll probably mull it over and the change would likely come for the month of September, if at all.

I'm fresh to patreon so I wanna get a feel for things, and I'd really appreciate your honest feedback! ♥
